What Respikast is used for
Respikast is used to prevent asthma symptoms, including those that occur during the day and
at night-time. It also prevents the narrowing of airways triggered by exercise. If you have

can be used in children 2 years of age and older, teenagers and adults.
Respikast tablets are not used to treat an acute attack of asthma. If an acute attack occurs,
follow your doctor's instructions for your reliever medicine, and keep taking your Respikast
each night or as prescribed.
As a preventive medicine for asthma, Respikast can be used alone or in combination with other
preventive medicines, such as inhaled corticosteroids. Your doctor may reduce your dose of
inhaled corticosteroid while you are taking Respikast .
